Our environment is almost entirely virtualized, so yes, extremely sequential. Each host has 2 or more 10Gbps NICs. So starting, suspending, moving, snapshoting and cloning a VM shows the limits in both. Our SAN is 4 years old and has tiered storage (10k SAS mainline HDDs and high-write SAS SSDs). We use cheaper SSDs in some instances. But there is a performance difference of 15%-25% between SAS and SATA and that can't be ignored.
